Write the condensed structural formula of the ester formed when each of the following reacts with methyl alcohol. Please provide a brief explanation of how you got that answer.
1. Formic acid
2. 2-methylpentanoic acid
Clausthalite is a mineral composed of lead selenide (PbSe). The mineral adopts a NaCl-type structure. The density of PbSe at 25C is 8.27g/cm^3. Calculate the length of an edge of the PbSe unit cell in Angstroms.
An unknown compound contains only carbon, hydrogen, and oxygen(CxHyOz). Combustion of 5.50g of this compound produced 8.07g of carbon dioxide and 3.30g of water.
suppose that cells are grown on amino acids that have all been labled with 13C at the alpha carbons. identify the atoms in cytosine and guanine that will be labled
suppose 7.70g of methane is mixed with 54.7g of oxygen . Calculate the maximum mass of water that could be produced by the chemical reaction
At 0.0C, if the volume of air is 1.8 mL and the pressure of the atmosphere that day is 665 mmHg, what is the number of moles of air?
At 28 ^circ rm C the osmotic pressure produced by the solution was 0.138 rm atm. What is the molar mass of the protein?
If you wished to prepare t-butyl propyl ether by a Williamson Synthesis, there are two possible combinations of materials you could choose as alternatives.
A 86 gram solution of silver nitrate contains 14 grams of AgNO3. What is the percent by mass of silver nitrate in this solution.
If the final solution has a chloride ion concentration of 1.80M which choice is closest to the concentration of the original SrCl2 solution?
The structure for methyl orange in acid solution is not as simple as protonation of the amine nitrogen. In fact, protonation of one of the azo nitrogens occurs resulting in a new, conjugated system.
Oxygen and hydrogen atoms combine to form molecules of wate. At the nuclear leveil, if one oxygen atom and one hydrogen atom were fused
name the four general types of carbonyl reactions. give an example of each including a detailed mechaism. use a propyl group next to a carbonyl in each example.
